MMBZ5243BTW_R1_00001

Overview

The MMBZ5243BTW_R1_00001 is a surface mount silicon Zener diode from the Panjit MMBZ5221BTW to MMBZ5267BTW series. It features a nominal Zener voltage of 13V with a tolerance range of 12.35V to 13.65V at an test current (IZT) of 9.5mA. The device has a maximum power dissipation of 200mW and operates within a junction temperature range of -55°C to +150°C. Packaged in an SOT-363 plastic case, it exhibits a maximum Zener impedance (ZZT) of 13Ω at IZT and a maximum reverse leakage current of 0.5μA at VR=9.9V.

Feature Summary

• Planar die construction for automated assembly suitability
• Lead-free compliance with EU RoHS 2.0 directives
• Green molding compound meeting IEC 61249 standards

Applications

• Voltage regulation circuits
• Overvoltage protection
• Reference voltage generation

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging details such as reel size or tape-and-reel specifications. Ensure that the component meets the required environmental standards and lead-free requirements for your manufacturing process before finalizing procurement orders.

Selection Notes

Select this component when a 13V Zener reference is needed in a compact SOT-363 footprint. Consider the 200mW power dissipation limit and the specific impedance characteristics at 9.5mA test current. Verify thermal derating requirements if operating near the upper temperature limits.

Part Context

This part belongs to the MMBZ52xxBTW series of surface mount silicon Zener diodes manufactured by Panjit International Inc. The series covers a wide voltage range from 2.4V to 75V, all sharing the same SOT-363 package and 200mW power rating profile.

Replacement Considerations

Direct replacements must match the 13V nominal voltage, SOT-363 package, and 200mW power rating. Verify electrical parameters such as Zener impedance and leakage current against the original datasheet specifications to ensure circuit compatibility.
